Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

• 原因：@Autowired注解注入時發現有多個實現類，而項目中並無多個實現類的情況，最終發現是由於Hateoas的新功能產生的

• 解決方案：在swagger配置文件中添加以下代碼

  @Primary
  @Bean
  public LinkDiscoverers discoverers() {
      List<LinkDiscoverer> plugins = new ArrayList<>();
      plugins.add(new CollectionJsonLinkDiscoverer());
      return new LinkDiscoverers(SimplePluginRegistry.create(plugins));
  }
